 Bug fixes
   - Support for matplotlib 1.5 color properties in the `display` module
+  - [#308] Fixed a per-octave scaling error in `librosa.cqt`
+
+New features
+  - [#279] `librosa.cqt` now provides complex-valued output with argument `real=False`.
+    This will become the default behavior in subsequent releases.
+  - [#288] `core.resample` now supports multi-channel inputs
+  - [#295] `librosa.display.frequency_ticks`: like `time_ticks`. Ticks can now dynamically
